The Idaho Transportation Department (ITD) Division of Aeronautics recognizes the significance of a proactive approach to ensuring aviation’s role in the statewide transportation system.  The Idaho Airport System Plan (IASP) provides the ITD-Aero an opportunity to stay abreast of changes in the aviation industry and to determine how Idaho’s airports should be positioned to respond to future needs and challenges.

Idaho’s State Airport System Plan provides input for federal planning documents.   The Federal Aviation Administration’s (FAA’s) National Plan of Integrated Airport Systems (NPIAS) is updated every two years.   The FAA provides money for eligible airport development from the Airport Improvement Program (AIP).  Airports must be included in the NPIAS for their projects to be eligible for AIP funding.   Recommendations from the Idaho Airport System Plan will be included in the NPIAS.

The IASP is the Idaho Transportation Department’s comprehensive plan for linking statewide aviation facilities with those of the nation and the world.   Idaho’s system plan also works in concert with Idaho’s Transportation Vision.  The Transportation Vision examines all of the state’s transportation needs and sets the direction for making improvements and investments in all modes of transportation.

Like the highway system, Idaho’s system of 126 public use airports are a critical component of the state’s transportation system. And, also like the highway system, constant maintenance and improvements are necessary to meet the needs and demands of the traveling public. Simply put, current aviation system needs far outweigh available funding.

The State Capital Improvement Program (SCIP) is tackling the challenge of targeting state and federal resources in a more strategic way by better identifying and prioritizing aviation related projects. This process helps ITD-Aeronautics and local governments communicate to decision-makers the need for continued and increased investments into Idaho’s airport system. The program is intended to be a continuous, multi-year funding program that will assess short-term (0-5 year) and long-term (5-20 year) airport improvement needs for the Idaho airport system. The SCIP is helping agencies including ITD-Aero, the Federal Aviation Administration (FAA) and local governments to better anticipate future airport development capital needs and to make strategic investments to maximize financial resources.

ITD-Aero is developing and implementing the program on two fronts:

  1. A program for airports eligible for FAA Airport Improvement Program (AIP) funds.
  2. A program for airports only eligible for Idaho Airport Aid Program (IAAP) funds.

For AIP eligible airports, the SCIP program is being developed in partnership with the Federal Aviation Administration (FAA) Northwest Mountain Region and the FAA Seattle Airports District Office (ADO). The Seattle ADO is the primary FAA regional Line of Business overseeing airport development and funding in the states of Idaho, Washington and Oregon. In support of this partnership, the FAA has provided ITD-Aero with a grant to develop an AIP eligible SCIP.

General Benefits

  1. Capture for the first time at the state level both the constrained and unconstrained needs of Idaho airports. This data will be used to demonstrate to state legislators and other local decision-makers the financial needs to maintain and enhance this critical component of the statewide transportation system.
  2. Use the process developed in partnership with the FAA for federally funded airports for non-federally funded airports within Idaho.
  3. Increase predictability, consistency, and efficiency amongst ITD-Aero, airport sponsors and FAA when prioritizing and distributing Idaho airport capital improvement funds.
  4. Eliminate duplication of efforts. ITD-Aero will be responsible for the annual collection of CIPs from airport sponsors, which will alleviate airport sponsors from having to duplicate communication with both the FAA and ITD-Aero.
  5. Maximize efficiency by designating ITD-Aero as the organizer of CIP submittals. ITD-Aero will then work with the FAA to provide a more timely response from the agencies back to airport sponsors regarding their CIP requests.
  6. Joint coordination with FAA Project Managers as part of the five year SCIP development process will result in:
    1. Increased resources for airport sponsors to discuss your individual airport CIP and airport needs.

    2. The ability of Idaho to work with the FAA and airport sponsors to better incorporate statewide aviation needs into the overall SCIP development process.

    3. More efficient use of available AIP funds to Idaho airports as well as the potential for increased access to certain AIP funds as a result of better SCIP planning.

    4. Create a proactive, continual planning process for years to come. This will result in a more sustainable airport system, enabling ITD-Aero, FAA and local governments to look ahead to determine how the system can continue to be improved and preserved.


As a new program within ITD-Aero, full development and implementation of this program is expected to take two to three years. Over the coming months ITD-Aero will be visiting with airports to discuss the program, answer any questions and gather input about existing CIPs.

The Idaho Airport Aid Program (IAAP) provides for the discretionary allocation of grant funds to Idaho airport owners.  

Only public entities are eligible to participate in the Idaho Airport Aid Program.   Any county, city, village, or agency designated in Idaho Code, shall be deemed an eligible public entities for the purpose of participation in the Idaho Airport Aid Program. 

The funds are derived from Idaho’s Aviation fuel tax.  The IAAP is a Trustee and Benefit program providing matching funds to municipal governments for public airport improvements. 

Allocations must meet high priority needs and achieve maximum benefit and use of available funds.   The allocation program is designed to provide the greatest and best utilization of limited Idaho Airport Aid funds and maximize availability of Federal funds. 

The primary goal of the allocation program is to further the proper development of statewide system of airports and fair distribution of aviation tax money.

It is a modest program with a budget that varies from year to year.   There are basically six areas where we provide assistance.

  1. Primary Airports – We provide about ±19% of our annual budget to our seven commercial airports.  Funding is calculated upon the relative level of activity.  This may be used to match any other source of funding.

  2. GA NPIAS Airports – We provide about ±40% of our annual budget to 31 NPIAS GA airports.   We provide half of the local match required for a FAA-AIP Grant.    This covers State apportionment funds, non-Primary Entitlement funds, and GA discretionary funds.

  3. GA non-NPIAS Community Airports – We provide about ±30% of our annual budget to 30 non-NPIAS airports.  These airports receive no AIP funding and must rely on the State of Idaho for assistance.   We pay between 50% and 90% of the project costs depending upon the size of the community.

  4. Airport Maintenance and Safety Supplies – We provide about ±1% of our annual budget to supply airports with cost effective maintenance items such as lamps, light fixtures, wind socks, lens and other items.   Simply, we purchase in bulk and provide the smaller quantities of items to the public airports at or below cost.

  5. Small Projects – We provide less than ±1% of our annual budget for one-time unscheduled and emergency projects that cost under $ 2,000.   This ranges from wind sock standards, to tie down chains, crack sealing, radio operated light switches, etc.

  6. Small Airport Planning Studies – We provide about ±9% of our annual budget to small communities and state-operated airports to prepare current airport planning documents.  We also provide a consultant and any airport information available in exchange for the airport operator seating a planning advisory committee.   Such studies usually include a Narrative Report with a Capital Improvement Program (CIP) and a Land Use and Zoning Plan as well as a drawing set including at least an Airport Layout Drawing, Airspace Drawing, Property Drawing, and a Land Use Drawing.

  The IAAP is administered according to the Idaho Administrative Code IDAPA 39.04.04.  This rule requires that an airport owner must have a State approved airport plan (section 200.01), and protective zoning (section 200.04) in place in order to participate in the IAAP.  However, if they do not have a plan or protective zoning in place, or if these need to be updated, the IAAP can provide funding for those items.

 The airport owner may use force account (in-kind) work as part, or all, of their required match for IAAP funded projects.  The value of the force account (in-kind) work shall not exceed the amount to the Sponsor/Owner’s designated match for this project.  The type, amount, and value of the in-kind work must be estimated and approved by the State before the start of work.   The owner may use their own internal rates, or the rates listed in the Idaho Transportation Department Standard Specifications for Highway Construction.  The airport owner must also show that the use of force account (in-kind) work is in the public interest and must demonstrate that it can accomplish the work with equal to or better quality, and for equal to or less than the cost of having it commercially done.   Additionally, volunteer labor, materials, and/or equipment must be listed as force account (in-kind) contributions.

The State of Idaho Transportation Department, Division of Aeronautics (ITD-AERO), provides information to airport owners located throughout the State that assists them in maintaining and operating their airports. The ITD-AERO has determined that providing information to airport operators on existing pavement condition would be beneficial. Each airport operator makes frequent decisions about the timing and type of maintenance and repair activities that should be applied to their pavements so the pavement has an acceptable surface operational condition and adequate load-carrying capacity.

To assist airport operators in making these necessary decisions ITD-AERO elected in the mid-1980s to implement a network pavement management system as one part of the overall State Airport System Plan. A pavement management system provides an efficient process for identifying pavements requiring maintenance and repair activities and for establishing project priorities. The system also allows the user to assess overall pavement network condition, to prepare and forecast the budgets required to maintain the network at an acceptable condition level, and to identify required maintenance and repair activities.

Having a network level pavement management system for the 45 airports included in the study allows the ITD-AERO and the Federal Aviation Administration (FAA) to assess overall airport pavement condition throughout the State, and to determine pavement deterioration rates, both at individual airports and globally for the state airport system. The implemented network pavement management system assists ITD-AERO and the FAA in identifying feasible maintenance and repair strategies for each identified project, and in prioritizing maintenance and repair requirements based on varying funding levels. Having a network pavement management system enables the ITD-AERO to best use the funds available for pavement maintenance and repair, and assists in optimizing pavement network condition.

This project objective is to develop a planning tool for the ITD-AERO that uses a rational basis for making decisions about pavement condition and funding allocations for pavement improvement projects. The project objective is accomplished by evaluating current pavement condition at the 45 airports included in the study. Approximately one-third of the airports included in the study are inspected each year resulting in every airport being inspected once in three years.

The Division of Aeronautics evaluates structures under the authority of Idaho Code 21-513 through 21-520 and Idaho Transportation Rule No. 39.04.02.   All proposals for structures in excess of 199’ or those of a lower height located near a public-use airport are evaluated for impacts on aircraft navigation.   Mitigation of aviation hazards typically involves marking and lighting of structures.   Proponents of vertical structures can contact the Aviation Technician if questions regarding location, height (and the need to notify the Division of Aeronautics of a proposal) arise during the project planning phase.   Notification of the Division of Aeronautics prior to construction best accomplished by submitting a copy of the FAA form 7460-1 to our office.   This form contains all the information the State of Idaho needs to accurately evaluate a structure and its location.   You can find a link to this form at:

* It should be noted that proponents of structures described above are required to notify the Federal Aviation Administration to allow that agency to evaluate the structure for impacts on the national airspace system .
